These four P’s of Product, People, Process and environmental Press have been used as frameworks by many creativity researchers and writers.
In a helpful overview article, Sandeep Gautam provides explanations of these concepts, and references to various creativity experts. Here are a few excerpts.
First, to start with the illustration: “Blind monks examining an elephant”, an ukiyo-e print by Hanabusa Itchō (1652–1724).
The story that inspired this artwork is basically that “a group of blind men (or men in the dark) touch an elephant to learn what it is like. Each one feels a different part, but only one part, such as the side or the tusk. They then compare notes and learn that they are in complete disagreement.” [Wikipedia]
Gautam concludes his article:
“In the end, it is important to realize that creativity is all things to all people, but still needs desperately, and would benefit from immensely, an integrative research paradigm; otherwise like the proverbial blind men and the elephant, we may end up getting narrow and useless conceptions of creativity and ignore the big elephant in the room.”
